DRAWBAR FOR CARS.

SPECIFICATION Aforming part of Letters Patent No. 498,329, dated May 30,1893.

Application led December 15, 1891. "Serial No. 415,103. (No model.)

To all whom it may concern:

Be it known that I, GEORGE W.'I`oMPK1Ns, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Drawbars, of which thefolfollowiug is a specification.

My invention relates to draw-,bars forrailway cars, and has referencemore particularly to improvements in the draft mechanism by which thedraw bar proper is held securely to the draft timbers, with capabilityof going and coming sufficiently to relieve the shock of buffing or of asudden draft.

The great difficulty' with draw-bars as heretofore constructed has been,that the lugs against which the follower plates of the drawbar properabut, and which are usually bolted to the inner sides of the drafttimbers, are incapable of withstanding severe buffmg of the carswithoutfracturing or snappingod the bolts which hold them'to thetimbers;

The prime object of my invention therefore, is to so construct andarrange and secure the said lugs, as to make themv practically as strongas' the follower plates themselves so as to be capable of withstandingeven unusually severe shocks.

With this ultimate end in view, my invention consists in certainfeatures of novelty in the construction and arrangement of parts ashereinafter fully described with reference to the accompanying drawingsand more particularly pointed out in the claims.

In the said drawings-Figure l, is a plan view of the draft timbersshowing .my improvement appliedv thereto. Fig. 2, is a longitudinalsectional View of the same taken onv the line 2, 2, Fig. l, showing oneof the timbers and the lugs with their tie-straps in side elevation, andFig. 3, is a perspective view showing the relative positions of certainparts l hereinafter more fully explained.

In the drawings, A, A, represent the draft timbers of any usualconstruction, between the inner ends of which is securely clamped asolid block B, whose under side, as well as the under sides of thetimbers A, A, is cut away on the profile shown in Fig. 2, for theattachment of the transom. This block B, extends from the rear or aftlugs, which will be presently described, to the tail ends of the drafttimbers, and is securely held in place by means of transverse boltswhich pass through it and the timbers, thus forming a Iirm abutment forthe rear lugs, and 4making the timbers practically of a solid piece attheir tail ends. I

Arranged between the timbers A, A, at their forward ends, is thedraw-bar proper D, of any well-known and suitable construction, upon theking bolt E, of which are sleeved two follower plates F,G, and betweenthese plates upon said bolt E, is located any suitable form of draftspring H, the bolt E, being held against withdrawal from the followerplate G, by means of a tail pin I, in the ordinary manner. Arranged foreand aft the follower plates F. G, are lug castings K. L, respectively,secured to the inner side of each of the draft timbers by means oftransverse bolts M. Each of these lugs as more clearly shown in Figs. 2and 3, is provided with two countersinks or depressions N, through whichare formed ythe horizontal bolt holes O, for the passage of the bolts M,such countersinksV being preferabh` of sufficient depth to whollyreceive the heads of the bolts M, so that the latter will be flush withthe face of the lug in order that they may not be struck by the draw-barproper.

P, are tie-straps which pass from the tops of the fore lugs to the topsof the aft lugs respectively, and are secured to such lugs by 'means ofvertical bolts Q, which pass through them and through each end of eachof the lugs, and also through similar tie-straps R, passing from thebottom of the fore lug to the bottom of the aft lug the horizontal boltsbeing arranged between the vertical bolts whereby the one set of boltswill reinforce the other when either bufng or draft strains areproduced. These tie-straps as shown in Fig. 2, are preferably bent overat their ends so as to form angular bends S, which embrace the cornersof the lugs and relieve the bolts Q, of considerable strain. Thetie-straps, however, if desired may be formed of asingle piece as-shownin Fig. 3, passing from the fore lug over and under that is to say,around the rear lug and back againV to the under side of the fore lug,and being secured to each lug by means of two bolts Q, as in the formshown in Fig. 2. This change simply involves the connecting loo togetherof the angular bends where they pass around the lugs at one end, asshown on the right in Fig. 3-such union of the angular bends beingpreferably eifected by forming the two straps integrally. The followerplates F, G, iitbetween the upper and lower tiestraps on both sides, andare adapted to abut against the fore and aft lugs K, L, respectively,and thus impart movement to the draft timbers.

In order that the lugs K, L, may be held with greater security againstlongitudinal movement, I provide each of them With an upright cleat orkey T, formed integrally therewith and fitting in complementary seats orsockets formed in the inner faces of the draft timbers.

Arranged on the under sides of the draft timbers, preferably midwaybetween the lugs K, L, is a tie-bar or brace U, which extendstransversely of the draft timbers, and is secured thereto by means ofvertical bolts V. This bar U, not only greatly stiffens the drafttimbers at this point, but serves for the further purpose of holding thedraft springs up into position with their coils concentric with theopenings in the follower plates, when the king bolt is withdrawn forrepairs.

'lo prevent the follower plates from wearing into the draft timbers, Iprovide each of the latter with a'chaiing plate W, let into it so as tobe iinsh therewith, and being secured in place by means of screws orbolts as shown.

\Vitl1 a draw bar thus constructed, the Strain of pulling or buiing isdistributed uniformly throughout the entire length of both the fore andaft lugs, and it is very simple and durable and easily applied withoutnecessitating any change in the construction of the draft timbers ordraw-bars proper now in use.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s-

1. In a draw-bar, the combination with the draft timbers and thedraw-bar proper arranged'between said timbers and having a followerplate thereon; of lugs secured to said draft timbers fore and aft saidfollower plate,

and tie-straps securing said lugs together, and passing around one ofthem substantially as set forth.

2. In a drawbar, the combination with the draft timbers, and thedraw-bar proper arranged between said timbers and having a followerplate thereon; of lugs secured to said draft timbers fore and aft saidfollower plate, and tie straps formed integrally and passing around oneof said lugs and being securedto the upper and lower edges of the other,substantially as set forth.

3. In a draw bar, the combination with the draft timbers, and thedraw-barproper having a follower plate thereon; ot' lugs secured to thedraft timbers fore and aft said follower plate, tie-straps extendingfrom the upper and lower edges of the fore lugs along the upper andlower edges of the aft lugs having angular bends engaging the outeredges of said lugs, and bolts passing through said tiestraps and lugs,substantially as set forth.

4. In a draw bar, the combination with the draft timbers, the draw barproper arranged between said timbers and having a follower plate thereonand lugs secured to said draft timbers fore and aft of said followerplate, of tie-straps securing said lugs together, having angular bendsengaging the outer edges of said lugs at one end, and being bent aroundsaid lugs at the other end, substantially as set forth.

6. In a draw bar, the combination with the draft timbers, the draw barproper having follower plates thereon, and lugs secured to said drafttimbers fore and aft of said follower plates, of a solid block arrangedbehind the aft lugs and being securely bolted between the draft timbers,`substantially as set forth.

7. In a draw bar, the combination with the draft timbers, the draw-barproper having follower plates thereon, and lugs secured to said drafttimbers fore and aft said follower plates; of the cross-brace U,connecting the timbers together between said fore and aft lugs, and asolid block arranged against the aft lugs being securely bolted betweenthe draft timbers, substantially as set forth.

8. In a draw bar, the combination with the draw bar proper havingfollower plates, and the draft timbers, of the two pairs of fore and aftlugs secured to said timbers respectively, each of said lugs having avertical boltv hole through each of its ends, and a number of horizontalbolt holes arranged between said vertical bolt holes, bolts passingthrough said horizontal bolt holes and the draft timbers, tie strapsarranged on the upper and lower sides of said lugs, and bolts passingthrough said tie straps and vertical bolt holes, substantially as andfor the purpose set forth.
